INTERNATIONAL WORKSHOP ON
WEATHER MODIFICATION TECHNOLOGIES

JNT University – Hyderabad, India


Weather Modification (cloud Seeding) is the treatment of individual clouds or storm systems for the purpose of achieving a beneficial effect without harming people or the environment.

Many countries like China, South Africa, Russia, Pakistan, United States, Canada, Australia, India etc. are attempting weather modification techniques for various purposes.

The most common intended effects of weather modification include precipitation increase (rain and /or snow), fog dispersal (visibility improvement) and hail suppression.

Over its history of 50 years, modern weather modification experiments involved projects of various types in nearly 50 countries around the world. Some individual projects have been in operation nearly continuously for decades, with a few operating for nearly 50 years.

Weather modification is being accepted as highly portable and flexible technology.

It doesn't require construction of large, permanent and costly structure, such as dams or water conveyance systems.

Project can be mobilized quickly and operations can be regulated, as water needs dictate or suspended very quickly, if hazardous weather conditions develop.


India has long history of operations for weather modification particularly in the states of Maharashtra, Karnataka and Andhra Pradesh.

The Government of AP has taken lead in promoting the activity and funded the operations in terms of application development and promotion of research.

The workshop held at JNT University in 2005 strongly recommended continuing the cloud seeding operations in Andhra Pradesh.

As such the Government, in its earnest desire to provide reasonable amount of water for augmentation of the upland and rain-fed area agriculture activities through rain fall enhancement, is carrying out the operations for the last 3 years.

The operations carried out during 2004-06 have yielded valuable data, significant results in terms of scope and identification of technologies for enhancement of rain fall, development of methods for validation, understanding the extent of influence zone and physics and chemistry of hygroscopic seeding and cloud dynamics.

Hon'ble Chief Minister of Andhra Pradesh Sri Y S Rajasekhara Reddy with all his commitment to the farmer and increase of agriculture activities in the state and with great vision and foresight ordered that the operations related to cloud seeding should be carried out for the next 5 years.

This will enhance the scope for application and basic understanding of the cloud dynamics with specific reference and intent to application to the agro-climatic and agro-ecological zone.

Andhra pradesh has proposed to allot about $5,000,000 for 2007 for conducting cloud seeding operations in the arid districts for the benefit of the farmers.
Howevever,only 3or 4 planes are used for warm cloud seeding by using Hygros and silver iodide perhaps involving mixed phase seeding as in Thailand.More emphasis has to be given to use ground generators because the aeroplanes cannot be present in all the places when seedable cloud cover is available due to depressions and deep depressions and other suitable weather conditions.International experts from China,thailand,South Africa,Israil and Texas must visit the state to help improve the cloud seeding operations to augment their effectiveness.
